It carries a 63 A ampacity and is rated for 690 V insulation voltage at pollution degree 3, which means it can handle the full rated current of the largest S0 motor-protective breaker without derating in typical industrial atmospheres. The screw-type terminals accept solid conductors up to 16 mm² and stranded up to 25 mm², so it covers the full wiring range for motor feeders up to that current. The terminal block is 43 mm wide, 74 mm tall, and 48 mm deep. It mounts below the S00/S0 breaker on the same DIN rail.","metaTitle":"Siemens 3RV2915-5B SIRIUS 3-Phase Supply Terminal, 63 A, 690","metaDescription":"Siemens 3RV2915-5B SIRIUS 3-phase supply terminal, 63 A ampacity, 690 V insulation voltage, screw-type terminals, fits S00/S0 breakers, active production.

The 3RV2915-5B is a dedicated terminal block for feeding the breaker from below; it has no direct second-source because its function is purely passive (power distribution).
